How much land does it take to support a human being? Boundaries of China superimposed upon those of the USA. Let's do the math again, but this time for the entire planet. The total land surface area of Earth is about 57,308,738 square miles, of which about 33% is desert and about 24% is mountainous. Subtracting this uninhabitable 57% (32,665,981 mi2) from the total land area leaves 24,642,757 square miles or 15.77 billion acres of habitable land.
The total land area of the earth is about 57 million square miles, so I'll bump that down to 50 million square miles of land habitable to mosquitoes (probably an overestimate, but I'm just looking for ballpark here). Next one would have to estimate how many mosquitoes inhabit each square mile on average. I've seen some areas where the mosquito density was upwards of 1 mosquito per 2-3 square feet, but I think that's a gross overestimate of the world as an average.
